PROBLEM TO BE SOLVED: To provide an alignment apparatus which precisely and easily align the measurement origin of the measurement reference coordinate of an inspection bench with a foot-type center point being the center of a standing position.SOLUTION: The alignment apparatus (stabilometer 100) including an inspection plate 11 on which a subjective person gets and a load measurement means (a load cell 12) for measuring the loads of a plurality of places acting onto the inspection plate 11, includes: a foot length measurement means (foot length measurement scale 41) which measures a foot length from the heel to the toe of the subjective person and an alignment means (origin center upright scale 42) aligning the measurement origin 13 being the center of the inspection plate 11 with the foot-type center point 16 of the subjective person on the basis of the foot length measurement value measured by the foot length measurement means.COPYRIGHT: (C)2010,JPO&INPIT【課題】検査台の計測基準座標の計測原点と立ち位置の中心である足型中心点とを正確かつ容易に一致させることのできる位置合わせ装置を提供する。【解決手段】被検者が乗る検査板11と、検査板11上に作用する複数箇所の荷重を計測する荷重計測手段(ロードセル12)と、を備えた位置合わせ装置(重心動揺計100)は、被検者の踵から爪先までの足長を計測する足長計測手段(足長計測スケール41)と、足長計測手段によって計測した足長計測値に基づいて、検査板11の中心である計測原点13と、被検者の足型中心点16とを位置合わせする位置合わせ手段(原点中心立位スケール42)と、を備える。【選択図】図2
